Certain hardware errors report a negative clock value in text logs.


The negative clock value is negative but has no impact to the system. The hardware issue needs to be investigated. Traffic disrupted while tmm restarts.


TMM was having trouble attaching to Cavium devices, and thus causing a lot of TMM restarts.



Fix Information

Fixed by printing unsigned using %u instead of %d.
